Rancho RS5000X 0″ Rear Lift Shocks for 2011-2022 Chevy Silverado 3500HD

Part Number: RS55379

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to significantly improve the ride quality of your heavy-duty truck. Engineered for the 2011-2022 Chevy Silverado 3500HD at stock height, these shocks feature a unique progressive engagement valving system that minimizes harshness during initial impacts. This design provides a smooth, durable street ride while maintaining the rebound control necessary for hauling and towing applications.

Features

• Cross-Tuned Technology: A specialized valve base system provides refined compression and rebound damping to ensure a balanced ride across varying road surfaces.
• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual increase in damping force to ensure maximum comfort during low-velocity piston travel.
• Gas Pressurized Twin-Tube: The nitrogen gas-charged chamber provides consistent performance by reducing aeration and oil foaming to ensure reliable damping under load.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical shield for the piston rod to ensure long-term seal integrity against debris.
